' I. LIGHT FIXTURE AND ACCESSORY.

Application filed December 24, 1927. Serial No. 242,332.

My invention relates to. light fixtures and accessories. More particularly my invention relates to means for supporting a globe and for sealing the globe so as to prevent dust, bugs, and the like from entering the structure.

The invention will be more readily understood from the following, specification and claims, reference being bad to the accompanying, drawing in which Fig. 1 shows a fixture comprising the features of the invention; Fig. 2 shows the holder in perspective; and Fig. 3 shows onesection of the holder in detail. Referring to the drawing, it will be seen that, the device comprises a hood 2 of insulating material such as porcelain. Embedded inthe element 2 are a latch hook 3 and a staple 4 which serves as a hinge for the holder, as will. more fully appear. The globe holder may assume any one of a number of forms; for example, the modification shown in Fig. 2 is constructed of two pieces of wire, one piece A forming the right half and one piece B forming the left'half. The

terminals 5 and 6 of the wire A are shown at the right, which terminals are located in the loop section 7 which, as will appear, forms a handle for the holder. The ter-' ininals 8 and 9 of the wire B are shown at the left and are shown more in detail in Fig. 3. It will be seen that the wire A is looped and then folded to form a pair of eyelets 10 and 11; the wire B is similarly looped and folded, but the ends 12 and 13 formed by the fold are compressed closely together so that they may be inserted in the eyelets 10 and 11. As shown in the drawing, the ends 12 and 13 are looped to form hooks within which the eyelets 10 and 11 hinge. The holder, therefore is in the form of a hinged structure. It will also be seen that the forward section 14 of'the element A is bent at an angle to a plane passing through the upper loop 15 of the section A. Similarly, the left hand section 16 of the element B is bent at an angle with a plane extending through the loop section 17 of the section B. The element 16 of the holder has its left extremity 18 folded to form a hooked portion which engages the staple 4 in the element 2, about which staple the holder hinges as shown in Fig. 1. In order to insert the globe 19 in the holder, Fig. 2, the screw 20 to allow the neck 21 of the globe to be inserted inv the holder between the sections A and B. Thereupon the screw 20 is reinserted in place and the nut 22 tightened so as to clamp the sections'A and B about the neck of the globe securely. When this has, been done theglobe and the holder as a unit.

are hung by meansof the hinge 18 from the staple 4, whereupon the globe and holder are raised by means of the handle 7 until :the mouth of the globe strikes the lower face of the element 2. -The handle 7 is thereafter sprung sufficiently to latch over the book 3 with the result that the clampedin position. Vith thestrueture described it isevident that the globe be readily lowered and raised whenever it is necessary "to trim the lamp.

globe is tightly In order to protect the rim of the globe I I provide awsuitable gasket consisting of a ring 23 of some resilient material such as felt, rubber, or-the like, suitably secured toa metal ring 24. This ring may be in the form of very thin copper ribbon. When copper ribbon or felt are used thetwo ele ments may be fastened together by sewing with ordlnary thread, as indicated in Fig. 1.

Obviously, therefore, by the provision of the gasket described the rim of the globe is protected against breakage as the result of its being swung with force against the element 2. The gasket also serves the purpose of in suring adust-proof Joint. In order to insure against the gasket falling from its position around the rim of the globe the ribbon 24-is provided with eyelets such as the eyelet 25 in order that a tie element 26 such as wire thread or the like may be used for holding the gasket in position.

It will be understood that while, in order to comply with the patent statutes, I have illustrated my invention in connection with certain specific embodiments, I do not wish to be so limited inasmuch as in view of the disclosure, variations may be readily constructed without.departing from the spirit of the invention or the scope of the claims contained herein. For example, a holder:

shown in Fig. 2 need not necessarily be made of bent wire, A structure similar to that shown may be readily the form of two unit metal elements to take the place of the elements A and B, which elements may be cast or otherwise produced.

What I claim as new and desire to secure by Letters Patent of the United States, is:

1. A globe holder having two sections formed of metal, each section being looped. and folded upon itself to form two folds, said sections being hinged together, the ends of one section being disposed in operative relation to each other whereby they maybe clamped together about the neck of the globe.

2. A globe holder having two sections formed of metal, each section being looped and folded upon itself toform two folds, said sections being hinged together, the ends of one section being disposed in operative relation to each other whereby they may be clamped together about the neck of the globe, one of the folds of one of said sections being formed into a hinge element and one of the folds of the other of said sections being formed into a latch element.

3. A globe holder having two sections formed of metal, each section being looped and folded upon itself to form two folds, said sections being hinged together, the ends of one section being disposed in operative relation to each other whereby they may be clamped together about the neck of the tions being formed into a hinge element and one of the folds of the other of said sections 7 being formed into a latch element, the other folds of said sections forming together the supporting structure for the globe.

4. A globe holder having two sections formed of metal, each section being looped and folded upon itself to form two folds, said sections being hinged together, the ends of one section being disposed in operative relation to each other whereby they may be clamped together about the neck of the globe, one of the folds of one of said sections being formed into a hinge element and one of the folds of the other of said sections being formed into ala'teh element, the other folds of said sections forming together the supporting structure for the globe, said latch-forming and l'iinge-forniing elements being disposed along planes diverging from plancs extending along the folds forming the globe supporting structure.

In witness whereof, I have herete set my globe, one of the folds of one of said sec-
